About this puzzle
9 islands on a 7×7 grid need 8 bridges between them. The biggest island number is 3.
2 islands need at least one bridge to every neighbour.
Where to start
A good first move: the island with the number 1 at row 5, column 1, which can see one neighbour.
Island arithmetic is enough here: compare each number with the neighbours it can see.
